The level of exercise is linked with the reduction of hospitalization and death in patients with chronic heart failure, according to a Henry Ford Hospital study.

Researchers measured the duration and intensity of exercise and found that increasing these parameters improved patients' quality of life and exercise capacity, and lessened their risk for hospitalization and death.

For example, patients who walk at 2 mph for 25 minutes two days a week likely lowers their estimated risk of hospitalization or death by about 10 percent, while patients who walks at 2.5 mph for 25 minutes five days a week likely lowers their estimated risk of hospitalization or death by about 25 percent.
